Complete removal 45 Fig 51S a perspective View the floating of the wing nuts permits the device to be commember detached from the device pletely disassembled for cleaning thereof or other Similar reference characters refer to similar purposes parts throughout the views The structure of the end plates and the shell 5 The device Shown in t accompanying draw between the same, held together by the bolts, mg comprisesgandopemtes as follows? forms a receptacle as mentioned above to re- The end plate'A has the groove ID in a side Ceive material be Operated uponthereoffor purposes appearing herein below and The Shell 13, as exemplified herein, has t alsohas the legs llapld lz th bbtt therepf rounded bottom it, preferably concentric with 55" forsupport of the device'and to elevatethe below a definite axis, and has the extrusion or dis- 55 charge holes 2! through this rounded bottom part. The shell is open at the top and is closed at each side by the end plates. The side walls of the shell are here made straight and divergent from each other to form a receptacle which progressively decreases in voluminal capacity downward of the receptacle. The grooves l0 and M are formed according to the required shape or contour of the shell.

The member E is shown as a one piece part having the body part 22 and the journal parts 23 and 2 3 on each longitudinal side thereof and concentric therewith.

The journal part 23 is shown. as journaled in the bushing 25 which is driven into the boss 26 on the end plate It. The outer end of the boss 26 closes the journal against leakage of the receptacle.

The journal part 24 is shown as j'ournaled in the bushing 2'5 and the packing 28 is introduced to seal the receptacle against leakage at this joint.

The longitudinal axis of the member E is parallel with the axis of the rounded bottom of the shell and spaced to one side thereof in a horizontal plane so that the member E is eccentrically journaled in the receptacle and the space 29 horizontally between the member E and one side wall of the shell is greater than the space at at the opposite side wall and the vertical space 3! between the member E and the rounded bottom of the shell is less or smaller than the space at the mentioned one side wall and greater or larger than the space at the mentioned opposite side wall.

The member 32- is shown as mounted in the slot 33 extending transversely through the member E and being of a width corresponding to the distance between the walls of the shell measured on the above mentioned horizontal plane.

The side 3 of the member 32 is of less length than the side 35 and the sides 36 and 31 slope from the respective ends of the sides 34 and 35 as shown.

The extrusion or discharge holes 2| are shown I as being staggered so that the member 32, in its operation in the receptacle, does not come opposite'a complete row of holes at any one stage of its rotation but will come opposite the holes more successively and thereby provide more smooth operation of the device and better discharge of material through the holes.

The operating handle 38 engages the end 39 of the member-E to rotate the same in the journals thereof and can be permanently or removably attached as desired. The grooves or pockets it are provided in the member E" to collect the skins or other fibrous component parts of the material which parts are not to be squeezed or forced out through the extrusion or discharge holes.

As to operation of the specific device shown and described:

Material to be operated upon,- beans for instance, is placed into the receptacle through the open top thereof.

Upon rotation ofthe member E by the handle 38, in a clockwise direction, or whatever means is provided for rotation of the member E, and

assuming that the operation starts with the member 32 located as shown in Fig. 4, the progressively decreasing distance between the circumference of the member E and the Wall of the shell at the right hand side of Fig; 4, moves the member 3'2 transversely in the member E through contact of the side 35 of the member 32 on the wall of the rounded bottom of the shell.

This movement of the members E and 32 progressively and volumetrically decreases the space between the members E and the shell and the beans will thereby be crushed or otherwise separated into the component parts thereof and forced or squeezed out through the extrusion or discharge holes and into a pan placed below the receptacle by the time the member E is rotated far enough so that the side 35 or the member 32 comes into the place where the short side 34 was at starting.

While the side 35 is so receding toward and into the member E, the side 34 is pushed outwardly of the member E, due to the contact of the side 35 on the eccentric bottom of the shell, and thereby takes hold of some of the beans in the receptacle and moves them around and into the space between, the member E and the bottom of the receptacle and separates and squeezes out of the receptacle, by compression thereof, the component parts as explained above although some of this separation is attained by the side 34 in taking hold of beans.

When the side 34 so takes hold of beans at the longitudinal middle part of the member E, an. agitation is created in the beans in the receptacle which agitation is quite helpful in stirring up the material in the receptacle sothat the sides of the member 32 can better take hold of the material.

When the side 35 leaves the bottom of. the receptacle and enters the top part thereof, it takes hold; of material all" the way along longitudinally of the member E and moves material into the bottom of the receptacle and out through. the discharge holes in a mamier similar to the operation of the side 3'1. Agitation of material in the receptacle is attained similar to the agitation produced or created by the side 34 as described above.

Theseparating of; the component parts of material' in the receptacle is attained first by the sides 34 and 35 taking. hold 01' some of the material and cutting parts thereof, as, for instance, cutting a number of beans, previous to moving the pieces into the bottom of the receptacle to be compressed therein and further separated. and squeezed out as is explained above.

This separating and squeezing also separates the skin or fibrous component. parts of the material from the meat thereof, as for instance, separating the skinof the beans from the meat. thereof, and meat is forced out throughthe discharge holes but the skins remain in the receptacle and are collected in.the grooves or pockets it-from where the same can be removed easily either through the top of the receptacle or by disassembling of the device as explained above.

- The member 32 can be removed individually through the top of the receptacle when the member E is rotated so thatthe side 35 of the member 32 is vertically disposed but can not fall out of the member E.

It is preferred that the parts of the-device be made of rust-proof material to prevent contamination of material operated upon and be made of acid proof material when acid material, such as the acid fruits, is to be operated upon.

' The device shown and described, upon operation thereof, separates into component parts-the material placed into the receptacle, forces or squeezes out of the receptacle the desired component parts, and-'retains withinthe receptacle,

for later removal thereof, the component parts which are not to be mixed with the desired parts.

I am aware that changes and modifications can be made in the structure and arrangement of parts shown and. described; therefore, without limiting myself to the precise structure and arrangement of parts as shown and described,

I claim:

1. A device of the character described including a receptacle for material to be operated upon having a discharge means, a member eccentrically Within said receptacle, and a single part movable in said member and having the material engaging ends thereof of different widths to engage material in said receptacle and to put different pressures thereon during one revolution of said member to force the material out of said receptacle through said discharge means with difi'erent pressures upon operation of said member.
